The FA-4 was a pilot droid model with a thin, spindly frame mounted on a wheeled unit. They had ball heads, and at over two meters in height were tall enough to pilot many starships, including Punworcca 116-class interstellar sloops.
FA-4 droids were utilized in the last decades of the Galactic Republic, and during the Clone Wars. The Sith Lord Count Dooku, head of the Confederacy of Independent Systems, owned an FA-4 which he used onboard his Punworcca 116-class interstellar sloop solar sailer. The droid piloted the Sith from the planet Geonosis to the planet Coruscant after the Separatists' defeat during the Battle of Geonosis. FA-4 units also worked on Coruscant itself, and around the time of the Battle of Coruscant, these droids bustled around the Senate Building and the Senate Office Building.
